Description
Replacing the injectors on your Duramax? Why replace the injectors and then put worn original lines and aging valve cover seals back into service? This package is built around the major components you'll already be working with during an LLY injector replacement, giving you a cleaner and more complete way to tackle the job. Bosch stock-replacement injectors handle fuel delivery, while fresh injection lines and valve cover gaskets address supporting components that are easy to overlook during a major repair. The Bosch injectors provide stock-replacement fuel delivery and OE-style fitment for the 04.5-05 6.6L Duramax. Pairing them with a complete Fleece Performance injection line set gives the new injectors fresh high-pressure fuel lines rather than relying on aging originals. Replacing the lines while the system is apart is a smart way to eliminate potential issues caused by worn, damaged, or contaminated lines and to ensure the fuel system is ready to support the new injectors. Getting to the LLY injectors requires removing the valve covers, making it the perfect time to replace the gaskets instead of reinstalling aged seals. The MAHLE valve cover gasket set is designed to meet OE specifications and provides a direct-fit replacement. With fresh gaskets and new fuel-system components going back together, you can complete the injector job without cutting corners on the parts surrounding it.

About Bosch
Browse Bosch Auto Parts Online by Make, Model, and Year. Bosch has long been a recognizable name in the automotive industry. For those unaware, vehicle manufacturers outsource a sizable amount of the components that go into the production of vehicles, and Bosch is one of the companies that have had long standing relationships with a plethora of manufacturers over the years to build numerous vital components. In the diesel industry, Bosch is most known for producing original equipment injectors and injection pumps for use in Ram trucks powered by a Cummins engine, Chevrolet and GMC's with a Duramax diesel, and Ford SuperDuty's sporting Powerstroke engines. Rest assured that if you purchase Bosch Fuel Injection parts from us that you are only getting Bosch certified new or Bosch certified reman parts with the full factory warranty.

For the diesel market, Bosch gained considerable notoriety with the design and implementation of the common rail fuel injection system found originally on LB7 Duramax’s, then two years later with the 2003 Cummins, and finally available in 2008 on the 6.4L Powerstroke. While this may have been when Bosch was most noticed in this industry, their roots go back much further, building the original equipment HPOP (High Pressure Oil Pumps) for early Powerstrokes, the VE and VP44 injection pumps on Cummins, and injectors throughout nearly all applications. For current era light duty diesels, basically you can nearly conclude that if fuel touches it, it was most likely originally built by Bosch.

And while we continue to mention injection pumps and injectors, its SO much more than that. As previously mentioned, if fuel touches it, you can be pretty sure that Bosch made it, including the Fuel Control Actuators (FCA) also known as an MPROP that are mounted to the injection pump, Rail Pressure Sensors, and even Pressure Relief Valves. They're all made by Bosch! And finally, outside the realm of fueling, we offer Bosch Wiper Blades (yes, they make those too) because, honestly, they make a really nice wiper blade that works.

And you won’t just find Bosch in factory parts. The majority of aftermarket manufacturers or rebuilders do not build components from scratch. Rather, they start off with factory Bosch core pieces, and then remanufacture those for a final product. So whether you're simply in need of a single injector, or needing a full set of matched injectors with injection pump, we've got you covered, and can typically get the parts out almost immediately to get your stranded truck back on the road again.
